Answer:
[tex]Pr = 0.55[/tex]
Step-by-step explanation:
Given
Represent the dataset with the following frequency table
[tex]\begin{array}{cc}{Item} & {Frequency} & {Fiction\ Book} &{11} & {Non\ Fiction\ Book} & {5} & {DVD} & {3} & {Audiobook} & {1} \ \end{array}[/tex]
Required
Probability that the next checkout will be fiction
From the above frequency table, we have:
[tex]Fiction\ Book = 11[/tex]
[tex]n =20[/tex] --- total
So, the probability that the next checkout item is a fiction book is:
[tex]Pr = \frac{Fiction\ Book}{n}[/tex]
[tex]Pr = \frac{11}{20}[/tex]
[tex]Pr = 0.55[/tex]

16. Chepkurui imports rice from the United States at an initial cost of 500US Dollars per tonne. He then
pays 20% of this amount as shipping costs and 10% of the same amount as custom duty. When the
rice reaches Mombasa he has to pay 5% of the initial cost to transport it to Nairobi.
(a) Given that on the day of this transaction the exchange rate was IUS Dollar = Ksh 76.60, calculate
the total cost of importing one tonne of rice up to Nairobi in Kenya shilings
Answer:
The total cost of importing a tonne of rice up to Nairobi was 51,705 Kenya Shilings.
Step-by-step explanation:
Since Chepkurui imports rice from the United States at an initial cost of 500 US Dollars per tonne, and he then pays 20% of this amount as shipping costs and 10% of the same amount as custom duty, and when the rice reaches Mombasa he has to pay 5% of the initial cost to transport it to Nairobi, given that on the day of this transaction the exchange rate was 1 US Dollar = Ksh 76.60, to calculate the total cost of importing one tonne of rice up to Nairobi in Kenya shilings the following calculation must be performed:
(500 + (500x0.2) + (500x0.1) + (500x0.05)) x 76.60 = X
(500 + 100 + 50 + 25) x 76.60 = X
675 x 76.60 = X
51.705 = X
Therefore, the total cost of importing a tonne of rice up to Nairobi was 51,705 Kenya Shilings.

Do you know what the FACTORS are of this generic rectangle
Answer: The two factors are x+7 and x+2
The polynomial factors to (x+7)(x+2)
=========================================================
Explanation:
In the upper left corner we have x^2. We get this by multiplying x with x
So,
x*x = x^2
This means you'll have x to the left of x^2, and another copy of x above the x^2. These new terms are outside the box.
Now ask yourself, what goes in the blank x times ___ = 7x. The answer must be "7" since x times 7 = 7x. So we'll write 7 above the 7x, outside the box. Up top, the x and 7 help form the factor (x+7)
Along the left side, the other factor is (x+2) for similar reasoning. Notice how we effectively have x times ___ = 2x and '2' must go in the blank. So a '2' must go to the left of the 2x.
Putting everything together, the two factors are (x+7) and (x+2).
Therefore, x^2+7x+2x+14 fully factors to (x+7)(x+2)
This is the same as saying x^2+9x+14 factors to (x+7)(x+2)
The order of multiplication doesn't matter.
The dividend is a factor of 60. The divisor is a factor of 18. The quotient is a multiple of 3. Use the numbers to find one possible solution. Numbers may be used once or not at all. Enter your answers in the boxes. 60, 2, 30 , 3, 8 , 9 , 12, 18 5 points
Answer:
The dividend is 360, divisor is 6 and quotient is 60.
Step-by-step explanation:
Factors of 3= 3*1
Factors of 18= 3*2*3
Factors of 60= 3*2*2*5
Taking LCM= 3*2*2*2*3*5= 360
60 is a factor of 360
The dividend is 360
If 360 is divided by 6 we get 60 which is a multiple of 3
and 6 is a factor of 18.
Therefore the dividend is 360 divisor is 6 and quotient is 60.
The volume of a cylinder is 128(pi)cm^3. The height of the cylinder is twice the length of the radius. Find the measure of the radius.
Answer:
128/2 = 64 which gives you the height
sq root 64 = 8 which gives you the diameter
8/2= 4cm which is the radius (answer)
To wash a window that is 12 feet off the ground, Wayne leans a 13-foot ladder against the
side of the building. To reach the window, how far away from the building should Wayne
place the base of the ladder?
feet. Real answer no links!!

Answer:
5 meters
Step-by-step explanation:
Based on the situation, it forms into a right triangle. So we will apply the Pythagorean Theorem here. The ladder acts as the hypotenuse while the height from the ground to the window serves as our side "a". We are tasked to solve for "b". Side "b" is the distance from foot of side a to the tip of side c which is the hypotenuse (ladder). We will derive the formula below to solve for b.
c = √( a² + b² )
c² = a² + b²
b² = c² - a²
b = √ ( c² - a² )
b = √ ( 13² - 12² )
b = 5 meters

Find the mean, median, and mode of 12, 9, 17, 15, 10
Answer:
Mean: 12.6
Median: 12
Mode: 9, 10, 12, 15, 17
Step-by-step explanation:
Mean: To find the mean you have to add up all your terms and divide your result by the number of terms you have. ((12+9+17+15+10) / 5)
Median: To find the median you have to organize your terms from least to greatest and then find your center term. (12)
Mode: Normally to find your mode would be to organize your terms from least to greatest and see which of your terms occurs the most. In this case all terms occur only once, making all your terms the mode.
a line crosses through (-6,-2)and (2,10) determine the slope and y intercept for this linear relationship
Answer:
3/2
Step-by-step explanation:
The formula to find slope is y - y all over x - x or (y-y)/(x-x)
Let's start with the y's: 10 - (-2) = 12
Now the x's: 2 - (-6) = 8
12/8 or 3/2 is the slope
Solve the proportion 40/z+1 = 15/6
Answer:
z = 15Step-by-step explanation:
[tex] \frac{40}{z + 1} = \frac{15}{6} \\ [/tex]
Cross multiply
That's
[tex]15(z + 1) = 40(6) \\ 15z + 15 = 240[/tex]
Send 15 to the right side of the equation
[tex]15z = 240 - 15 \\ 15z = 225[/tex]
Divide both sides by 15
[tex] \frac{15z}{15} = \frac{225}{15} \\ [/tex]
We have the final answer as
z = 15Hope this helps you

Answer: x =67
Step-by-step explanation:
The equation to solve this is (x - 22) + 135 = 180
1) To solve for x, you must remove the parenthesis
x - 22 + 135 = 180
2) Simplify the equation...
x - 113 = 180
3) Simplify the equation
180-113 = x
3) Subtract to solve
180 - 113 = x
x = 67
Answer :
As shown in the figure the angles x - 22 and 135 lie on a straight line . So we may solve it using linear pair property that states that the sum of angles lying on a straight line is 180° .
( x - 22 ) + 135 = 180°Remove the brackets x - 22 + 135 = 180Subtract 22 from 135 and as 135 is is greater than 22 the sign will be positivex + 113 = 180Subtract 113 from both the sides x = 180 - 113x = 67°Thus the correct answer is option d that is x = 67

What is the value of x?
Answer:
x = 95
Step-by-step explanation:
angles that form a straight line add up to equal 180
Thus, x + 85 = 180
180 - 85 = 95
Hence, x = 95
